It isn't just governments and automakers working on reducing air pollution. Creating surface coatings that can absorb nitrogen oxides, usually titanium dioxide, has been a focus of several companies in several countries, and their products have been used on architectural tile, roofing tile and paving in England and The Netherlands.


The fight against pollution may soon take the fashion industry by storm as your clothes may clean up the mess your car puts out.


Researchers at the Eindhoven University of Technology (EUT) may be on the brink of discovering a breakthrough that will lead to reduced pollution and cleaner air for all. According to the EUT, a roadway made of concrete blended with titanium dioxide can effectively remove up to 45 percent of the nitrogen oxides that it comes in contact with. The titanium dioxide, a photocatalytic material, captures airborne nitrogen oxides and, with the aid of the sun, converts it to nitrates that are harmlessly


Whether or not you believe in global warming, nitrogen-oxides, or NOx, definitely does contribute to acid rain and smog, which are not debatable. Because NOx is emitted in large quantities from the exhaust of diesel engines, something needs to stop it from entering our atmosphere. One way to do this is with urea, which is being used in the Bluetec systems installed by various automakers. Because people don't like to think about carrying around a container of urea (think urine, although it is usu


New ACE Institute in Japan claims to have devised some new technology for diesels that they are claiming reduces nitrogen oxide emissions by up to eighty percent when the engines are fueled on canola-based biodiesel. They are using a mix of exhaust gas recirculation and high turbocharger boost to triple the combustion pressure. New Ace has been testing different combinations of EGR, boost, injection pressures and variable valve timing strategies, to optimize diesel efficiency and emissions. Hino
